installation method of this CHDK is the same as standard or non-trivial like on A650IS?

As this camera is also DryOS-based, the installation is the same as for A650, A720 & SD870.
(There is no PS.FIR in the package, so you have no option ;) )

;) 

No one has posted anything here about it, so I was  just wondering if  I needed to dust off the old IDE.

It will probably work if you copy platform/s5is/sub/101b to platform/s5is/sub/101a, copy the 1.01b ASM code parts from the 1.01a firmware dump into boot.c and capt_sec.c (should be straightforward) and adjust the addresses in stubs_entry_2.S and stubs_min.S. The differences are probably minor so locating the code/addresses shouldn't be too big a problem. It's just time-consuming and dull work (in my opinion :p). Oh yeah, and you'll have to make the ASM work, too. Some constructs/opcodes as recognized by IDA are not or cannot be accepted by the assembler.

Maybe I'll do it if nobody starts this within a short time, but I'd rather concentrate on further RE of the 1.01b firmware and getting a better understanding of how things work.

Hey DataGhost, your build 51 is working pretty well on my S5IS. I have encountered a couple of interesting issues, though:

  • As you noted above, [Shoot] to run a script freezes the camera, and then it crashes. (Haven't tried toggling the flash up and down yet.)
  • There's a white rectangle poking up into the bottom of my screen during record mode. It stretches from the left edge to the middle, but it's only a few pixels high, maybe 10. Any idea what it is?
  • I can't start in record mode, even if I flip the [On] lever that direction to turn on the camera. It always starts in Playback mode instead. Repeating the [On-Record] push gets me into Record mode, though.
  • The native histogram floats over the CHDK menu. Not a biggie, 'cause I soon turned it off in favor of the CHDK histo.
  • I did experience at least one other crash, can't remember where. Is there any way for me to capture debugging info, or is it too late by the time the crash happens? :-P
